The challenge is\r\nto achieve sufficient signal integrity with low heat load processing. In this\r\ncontext, we demonstrate the opto-electronic bias and readout of a commercial\r\nfour-pixel superconducting nanowire single-photon detector array using a\r\ncryogenic photodiode and laser. We show that this approach has a similar system\r\ndetection efficiency to a conventional bias. Furthermore, multi-pixel detection\r\nevents are faithfully converted between the optical and electrical domain,\r\nwhich allows reliable extraction of amplitude multiplexed photon statistics.\r\nOur device has a passive heat dissipation of 2.6mW, maintains the signal rise\r\ntime of 3ns, and operates in free-running (self-resetting) mode at a repetition\r\nrate of 600kHz. This demonstrates the potential of high-bandwidth, low noise,\r\nand low heat load opto-electronic interconnects for scalable cryogenic signal\r\nprocessing and transmission.","lang":"eng"}],"date_created":"2024-04-25T11:12:07Z","status":"public","date_updated":"2024-04-25T11:13:39Z"}
